There are many types of azuki beans, such as red beans, red beans, bamboo beans, eyebrow beans, and miscellaneous beans. They contain quite a lot of nutrients, and some of them also have medicinal value (such as Chixiaodou, etc.), which is a popular high-quality food for people in both urban and rural areas. Appropriate development of adzuki bean production can not only increase income, but also obtain ecological benefits from land use. In the past, sporadic scattered planting was widely used throughout the country, and management was extensive. In addition, the varieties were mixed and the yield was generally low. Therefore, corresponding cultivation measures must be taken to achieve high yields. 1. Selective rejuvenation: The long-term self-retaining soybean adzuki bean varieties, most of which exhibit mixed degradation and deterioration, should be systematically purified and rejuvenated through the “single plant selection method” or “ecstasy removal quick selection method” respectively. In the selection of varieties, it is better to use upright or semi-herbate early and mid-maturing varieties. Second, intercropping rotation: Adzuki bean and cassava, corn and other high-stalk crops should be interplanted in order to make full use of the land. During intercropping, pay attention to the proportion of space occupied by the two. Generally, the spacing of high-stalk crops can be as wide as 2 meters to prevent the growth of beans and vines. In addition, the adzuki beans should not be used as continuous crops, and care should be taken to rotate with other non-legume crops. Third, reasonable dense planting: Adzuki beans suitable for spring or summer sowing. Spring sowing should select ripe varieties, the suitable spacing of the plants is about 50 cm 20 cm; the summer sowing time generally does not exceed the end of July, and the early varieties are appropriate, and the row spacing can be slightly denser than the spring sowing. Planting adzuki bean usually uses on-demand, sowing 2-3 seeds per hole. After sowing, cover it with appropriate amount of composting soil and pay attention to watering and moisturizing. Fourth, to strengthen management: the early growth of adzuki bean, the main grasping the whole seedlings, strong seedlings, wait until it grows 3-5 true leaves, in time for the thinning, combined with weeding, leaving 1-2 strong seedlings per hole. The nitrogen fixation rate of the nodule of bean Bean accounts for about 2/3 of its own N requirement. Therefore, based on the application of organic fertilizer, it is also necessary to pay attention to the appropriate application of N and P fertilizers. In particular, the amount of fertilizer required during flowering is greater. Topdressing nitrogen and phosphate fertilizers can promote flowering and pod growth. In the later period of childbirth, measures should be taken to prevent lodging, ensure soil moisture, and increase grain weight. In addition to avoiding waterlogging in fields, creeping varieties can also be introduced by cultivating seedlings to prevent them from spreading to the ground so as not to affect photosynthesis and seed setting.

API

what is API?

High-purity plant monomer refers to one or more single chemical components with specific biological activity or pharmacological effects extracted from plants, and its purity is usually high, meaning that the content of the component in the extract reaches a certain percentage, and the content of other impurities or irrelevant components is low.

These plant monomers are usually secondary metabolites of plants, such as flavonoids (flavonoids), alkaloids (alkaloids), terpenoids (terpenoids), phenolics (phenolics), etc., which play a variety of physiological functions in plants such as defense, signal transduction, and antioxidant. Due to their pharmacological activity, high-purity plant monomers are often used in pharmaceuticals, health products, cosmetics and other biotechnology products.

For example, Naringenin is a high-purity plant monomer extracted from citrus plants with antioxidant and anti-inflammatory activities; Corosolic acid is a high-purity active monomer extracted from loquat leaves, which is considered to be effective in treating type 2 diabetes and obesity.

Extraction and preparation of high-purity plant monomers usually require a complex separation and purification process, including extraction, column chromatography, crystallization, recrystallization and other steps to ensure the purity and activity of the final product. These processes may be required by specialized biotechnology companies.
